Scenario: "Generating and sending an SMS message"

Via an internal data array, the FB "SMS_Meld" function block generates a configu-
rable text message using the Message_No input variable and sends it to a recipi-
ent that is assigned to this variable.

(e.g. = )
The Message_No variable contains the message number that is necessary to
generate an SMS message. Using this variable, the associated telephone number
and message text are determined from a total of four arrays.
Two of these lists are linked to one another:
The ptrTelefonnumber and Telefonnumber lists are used to determine the tele-
phone number.
The ptrText and Text lists are used to determine the message text.
Depending on the value of the Message_No variable, the number is now deter-
mined from the ptrTelefonnumber and ptrText lists, which then defines the posi-
tion in the list in Telefonnumber and Text.
In this way, the information necessary for the SMS message is determined (tele-
phone number and message text).
By reconfiguring the indices and contents of the arrays, you can create any alloca-
tion and individually design the SMS message.
